No longer changes the video quality.

Automatic theater mode doesn't work.

For some reason it keeps switching to normal mode instead of theater, even when I ask it to stay in theater mode. Other than that, pretty great!

Thank you for adding this extension. It has a feature Google refuse to implement. It is so stupid how Youtube doesn't let you set a preferred resolution

No longer works.

Seems not working any more?

It used to work fine a year ago. Now it's not working correctly :(

Now, it makes Youtube buffer repeatedly and get stuck sometimes too even with same video quality.
Just disabling extension causes the buffering to be unstuck even though video quality or any other setting is unchanged.

It used to work fine couple of years back.

unfortunately it does not work for the option i downloaded it for - it does not change the quality/resolution of the youtube video at all, but it does set the size of the video to the specified one.

无法控制视频画质

Works at what it does, but I can't get the settings to open again to change them, and if you set a playback speed it resets to that on every new video even if you change the speed and wanted that same new speed on, say, a whole playlist. So, doesn't suit my needs.

COOL

No reason to request your data for all websites. This reeks of keylogger/malware or other security nightmare and should be removed from the mozilla store.

it's great!!

Minimal and useful, but currently broken. Also needs the ability to select default fps and secondary resolution if primary selected resolution is not available for video. I selected 1440p, but my videos keep starting at 480p when 1440p is not available, and most videos don't 1440p.
